SPECIFICATION forming part of Letters Patent No. 750,241, dated January19, 1904.

Application filed May 19, 1903. Serial No. 157,878. (No model.)

To all whom it may concern.-

Be it known that I, CARL F. BUCK, a citizen of the United States,residing at Salt Lake City, in the county of Salt Lake and State ofUtah, have invented new and useful Improvements in Spreading-Machines,of which the following is a specification.

The objects of this invention are to spread ores or other materials in asubdivided state, such as coal, wheat, corn, &c.

At ore-smelting plants various kinds of ores are bedded, the bed beingmade up in several kinds of ores in layers, one above another. At thepresent time this is done by hand. A level surface is prepared inclosedon all sides, forming a bin, and over this bin runwaysare prepared.Workmen wheel the ore in barrows and dump it on the floor below, whereit is spread out with shovels.

The accompanying drawings illustrate my invention, in wliich- I Figure 1is a bin and the mechanism connected horizontally therewith. Fig. 2 is aside elevation of the invention, partly in section. Fig. 3 is anenlarged plan of the top of the axle and hub carrying the spreader-arms.Fig. 4 is an enlarged vertical section of the same on line at w of Fig.3, and Fig. 5 is an enlarged elevation of the tank-door.

My machine is preferably located, under a railroad-track A, and consistsof a large uncovered tank or bin B, with preferably a concrete bottom. Acentral vertical frame C, having guides c 0, stands in the middle of thebin, its upper end being secured to a horizontal beam C, whose other endis supported on a post T. A vertical hollow axle D surrounds the frameC, having interior vertical recesses (Z d to engage the guides 0 c onthe frame C. A hub E, carrying radial arms F, rotates on the axle Dbetween the collars 0Z d on the i The arms F are preferably made ofmetal, and wooden extensions ff are secured to the under side of saidarms and project lengthwise beyond them almost to the sides Ashortprojection f on the end of each extension f stands at a right anglethereto.

The axle D is moved vertically by means of chains G, attached to eyes gon said axle. Said chains G pass over wheels H H, keyed on a shaft h,which is actuated by mechanism through wheel I. The shaft h is journaledin bearings on the beam C. On the same shaft h is a wheel 2', carrying achain 7a, which extends downward outside of the bin and is at tached toa horizontal frame L, which carries.

a sprocket-wheel m and two idle wheels n n.

A continuous chain 0 passes around a groove f on a band f whichencircles the ends of the arms F F. The sprocket-wheel m is actuated bypower through the drum 1), bevel gear-wheels q and r, and the shaft S,whose upper end has a bearing at s on the post T, its lower end and theadjacent mechanism having a base-support at t. Theshaft S is angularexcept at its journal-bearings, and the hub m of the sprocket-wheel m isalso angular and fits loosely upon it. The revolution of the shaft itraises or lowers the hub E and the frame L, and the revolution of thesprocket-wheel m rotates the band f and the arms F F. A vertical slot Uat the side of the bin permits the descent of the-frame L and the chain0. This slot U is closed by a vertically-sliding door V, attached toframe L, said door entering the pit W in its lower positions. are maderemovable in sections 1: o, to be taken out when the bin is to beemptied. The arms F may be made either straight or curved, as desired.

To prevent the material from getting into the hub E,I provide aliquid-sealed dust-guard composed of an annular groove e around the Theupper portions of the door V' bottom of the axle to be filled with wateror other liquid, into which extends the lower edge of a band e, attachedto the lower edge of the hub E. At the upper joint the groove .2 isattached to the hub, and the band 6 encircles the upper collar of theaxle. e e are overlapped and protected from above by shelves or roofs ee.

In operation the hub E and frame L are elevated and the material isdumped into the bin from the car above. It will form in piles, as y y.The arms F are then caused to rotate, and the hub and frame L aregradually Both grooves lowered until the material is spread out evenlyin the bin, as at The hub and frame are then hoisted and the operationis repeated. The projections f on the ends of the pieces f prevent thematerial from sliding off and piling up against the bin. To empty thebin, remove a section of the door V and continue the revolution of thearms, at the same time lowering the hub and frame L. This pushes thematerial out to the periphery of the bin and forces it through theopening U, already described. I

I do not limit myself to mechanism operating the arms F F which requiresan opening U in the tank, because a system of cords and pulleys may beused to move the arms,which would transmit the power over the side ofthe bin; but the connection shown is preferred.

Having described my invention, what I claim is-- 1. A spreading-machinecomprising a vertical frame having exterior vertical guides, an axlehaving interior recesses to engage said guides and vertically movable onsaid frame, a hub on said axle, horizontal arms on said hub and means toraise and lower and to rotate said hub and arms as specified.

2. In a spreading-machine having arms carried by a hub on an axle whichis vertically movable on a frame, a cross-beam at the top of said frameproperly supported, a horizontal shaft having bearings mounted on saidcross-beam, wheels keyed on said shaft,chains carried by said wheels,eyes on said hub to which said chains are attached, and means to revolvesaid shaft whereby the said hub is raised and lowered for the purposespecified.

3. In a spreading-machine a bin, a central vertical frame therein, armscarried by a hub on an axle which is vertically movable on said frame, aband around the outer ends of said arms, an exterior groove on saidband, a continuous chain in said groove passing through a vertical slotin said bin and around a sprocketwheel, and means to actuate saidsprocketwheel, for the purpose herein set forth.

4. In a spreading-machine having abin with vertically-movable revolvingarms therein and a vertically-movable frame carrying part of thearm-revolving mechanism, a vertical door in said bin fixed'to said frameand vertically movable therewith for the purpose described.

5. In a spreading-machine a vertical axle having collars at its upperand lower edges, a hub on said axle between said collars, an exteriorannular groove (1 on the lower edge of said axle, a band a on said hubwhose lower edge enters said groove, an annular groove 6" near-the upperedge of said hub, a band a" on the upper collar of said axle whose loweredge enters said groove 6 and roofs to overlap said groovessubstantially as herein set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CARL F. BUCK.
